GridLayout不能均匀地扩展元素 [英] GridLayout does not expand elements evenly

问题描述

我正在尝试使用GridView将屏幕分成六个相等的部分.问题是它在模拟器中正确显示，但是当我从电话查看它时，空间分布不均匀.是什么导致这种现象?

i am trying to use GridView to divide the screen into six equal pieces. The problem is that it displays properly in the emulator but when i view it from the phone then the space is distributed unevenly. What could cause this behavior?

我已经使用API​​ 21& API 22手机.

I have tested this with API 21 & API 22 phones.

仿真器与电话:

这是我的xml:

推荐答案

据我所知，布局权重仅适用于LinearLayout，但是您正在使用RelativeLayout.尝试切换它.

As far as I know, the layout weight works only with LinearLayout but you are using RelativeLayout. Try to switch it.
